The underground pop music scene in Iran thrives via the Internet despite increasingly repressive efforts by the nation's censorship bureaucracy to keep this tasty forbidden fruit away from Iran's largely under-30 population. Western genres including rock, rap, and hip hop are revamped in a Persian mode, with influences ranging from the poetry of Hafez to the Koran. Assorted bands and performers (all male, since the solo voices of women are strictly forbidden) strut their stuff in this engaging documentary, including alt-rock band O-Hum; rappers Souroush, and Reveal; and electronic band Atma.
